Timing is everything!

True story:
Playing in the kitchen, the big kids were hiding to try sneak up on me (not very well, mind you) and to jump out and scare me. I was pretending to ignore them - looking in the pantry for something or other. Dad was in on the joke...
Then, I literally shrieked and jumped, just the reaction they were looking for, only I intended to fake it. I didn't have to.
At just the moment the big kids were getting ready to "scare" me, one of the babies banged the metal loaf pan on the ceramic tile floor at the very moment the kids jumped out.
Haven't laughed so hard in ages. I doubled over laughing so hard. It was a good day.
